The provided text describes the 510(k) summary for the Arthrex VAL and VAL KreuLock™ Compression Screw System. This document outlines the device's technical specifications, indications for use, and a comparison to predicate devices, primarily focusing on demonstrating substantial equivalence through various mechanical and material tests.

However, there is no information within this document that describes a study involving an "AI device" or "algorithm." The document pertains to a medical device for bone fixation (screws), not a diagnostic or AI-powered imaging/analysis tool. Therefore, it does not contain the details typically sought when asking about acceptance criteria and study designs for AI/algorithmic devices, such as:

• A table of acceptance criteria and reported device performance (in terms of AI metrics like sensitivity, specificity, etc.)
• Sample sizes for test sets of AI data
• Data provenance for AI training/test sets
• Number of experts for ground truth establishment for AI
• Adjudication methods for AI ground truth
• Multi-reader multi-case (MRMC) studies for AI assistance
• Standalone performance of an AI algorithm
• Type of ground truth used for AI models
• Sample size and ground truth establishment for AI training sets

To directly answer your request based on the provided text, the answer is that the given document does not contain the information you are asking for, as it is not about an AI/algorithmic device.

The "Performance Data" section of the document describes the following types of tests for the mechanical bone screws:

• Mechanical Testing:
  • Pullout testing
  • Cantilever testing
  • Pushout testing
  • Head locking testing
  • Compression testing
  • Torque testing
  • Axial pullout analysis
  • Torsional strength testing
  • Driving torque testing
  • These tests were conducted in accordance with ASTM F543 Standard Specification and Test Methods for Metallic Medical Bone Screws to demonstrate that the changes do not affect performance and that the proposed devices are substantially equivalent to the primary predicate device.
• MRI Compatibility Testing:
  • MRI force, torque, and image artifact testing were conducted in accordance with
    • FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment"
    • ASTM F2052 (Measurement of Magnetically Induced Displacement Force)
    • ASTM F2119 (Evaluation of MR Image Artifacts from Passive Implants)
    • ASTM F2182 (Measurement of Radio Frequency Induced Heating near Passive Implants)
    • ASTM F2213 (Measurement of Magnetically Induced Torque on Medical Devices)

The acceptance criteria for these mechanical tests would typically be defined by the relevant ASTM standards and comparative data against the predicate device to demonstrate equivalent or superior performance in the specified mechanical properties. The study "proves" the device meets these criteria by showing that the results of these tests fall within acceptable ranges as compared to the predicate device.

To reiterate, if you're looking for information specific to AI/algorithmic device acceptance criteria and study designs, this document does not provide it because the device described is a physical bone screw system.

Subject of this premarket notification is an extension to the EVOS family of plates and screws, the EVOS Small Fragment Plating System. This system features similarities to existing Smith & Nephew small fragment plates (TC-100 Small Bone Plating System, PERI-LOC Plating System) and also shares some instruments and implants from the existing EVOS MINI Plating System. It is comprised of a variety of locking and non-locking 2.7mm and 3.5mm straight plates as well as 3.5mm locking and non-locking screws and 4.7mm non-locking osteopenia screws.

The provided document is a 510(k) premarket notification for a medical device (EVOS Small Fragment Plating System), not a study analyzing AI performance. Therefore, I cannot extract information related to AI acceptance criteria, sample sizes for test/training sets, expert adjudication methods, MRMC studies, or standalone algorithm performance.

However, I can extract the acceptance criteria and study descriptions for the mechanical performance of the physical EVOS Small Fragment Plating System, as detailed in the document.

Here's the information based on the provided text, focusing on the mechanical testing of the device itself:

1. A table of acceptance criteria and the reported device performance

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size: Not explicitly stated for each mechanical test. The document mentions "worst-case designs" for FEA and fatigue testing, and specific sizes of screws (3.5mm, 4.7mm) for others. Typically, mechanical testing involves a limited number of samples (e.g., 5-10 per test condition) to satisfy a statistical confidence level or regulatory requirement, but the exact numbers are not provided here.
• Data Provenance: Not applicable as these are pre-clinical (benchtop) tests of the device's physical properties, not clinical data from patients. The testing was conducted by Smith & Nephew, Inc.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

Not applicable. These are engineering and mechanical tests, not analyses requiring expert human interpretation or ground truth establishment in a clinical sense. The "ground truth" is defined by the objective measurement of mechanical properties against predetermined performance standards, often based on existing predicate devices or industry standards like ASTM.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This is not a study involving human interpretation or adjudication. The results are quantitative measurements against objective criteria.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This document describes the mechanical testing of a medical implant, not an AI or diagnostic imaging device.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This document describes the mechanical testing of a medical implant, not an AI algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for the mechanical testing is based on:

• Performance of legally marketed predicate devices. The acceptance criteria consistently refer to being "similar or superior" to predicates.
• Adherence to industry standards (e.g., ASTM F543 for screw testing).
• Compliance with FDA Guidance documents for sterility and endotoxin testing.

8. The sample size for the training set

Not applicable. This is not an AI study requiring a training set.

9. How the ground truth for the training set was established

Not applicable. This is not an AI study requiring a training set or its associated ground truth establishment.

Explanation: The document explicitly states "Performance Data" and then details "Pre-clinical testing included four point bend fatigue testing of plate constructs with appropriate accessory devices." It then states that "Substantial equivalence is based on similarities in design features and overall indications for use" with the predicate devices. This implies that the acceptance criteria for these accessory devices revolved around demonstrating sufficient mechanical strength for their intended orthopedic application and proving they are functionally similar to previously cleared devices.

2. Sample size used for the test set and the data provenance

• Sample Size: Not specified. The document only mentions "plate constructs" without providing the number of samples tested for the four-point bend fatigue tests.
• Data Provenance: Not explicitly stated, but it's a pre-clinical study, meaning it was conducted in a lab setting by the manufacturer (Smith & Nephew, Inc.). It is retrospective in the sense that the testing was completed before the submission to FDA.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. This is a pre-clinical, mechanical performance study, not a study involving human interpretation or clinical outcomes data that would require expert ground truth establishment.

4. Adjudication method for the test set

Not applicable. There was no human interpretation or decision-making in the testing that would require adjudication. The testing involved mechanical measurements.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
